Management commentary

“We are pleased with our strong second quarter results, which were achieved through disciplined execution and resilient end-market demand. We set new quarterly records for net sales, adjusted EBITDA and adjusted net income per diluted share, demonstrating the strength of our brands and impact of our ongoing commitment to operational excellence and cost management. I want to thank our employees for their continued dedication and effort in supporting our customers and delivering value for all our stakeholders,” said Paul McAndrew, President and Chief Executive Officer of Mueller Water Products.

“We delivered another quarter of strong margin growth, with adjusted EBITDA margin improving 210 basis points year-over-year, supported by our team’s execution and commitment to delivering value for customers while enhancing efficiencies across our operations and supply chain. As we navigate increased uncertainty and ongoing external challenges, we remain focused on providing outstanding customer service, driving operational efficiencies and proactively managing our supply chain. Based on our outstanding performance through the first half of the year and our current expectations for the remainder of the year, we are raising our fiscal 2026 outlook for adjusted EBITDA.”

Guidance and what it implies

The press release does not publish a formal revenue forecast, but the raised outlook for adjusted EBITDA indicates management expects continued earnings quality improvement and a favorable revenue trajectory for fiscal 2026. The focus remains on margins, efficiency, and a constructive balance sheet as the company navigates external challenges.

Context for Mueller Water Products and peers

Mueller Water Products operates in the North American water infrastructure space, a domain tied to municipal and residential water projects, replacement cycles, and ongoing modernization. The quarter’s results showcase two lasting themes: pricing/mix power that supports margins and a resilient top line, paired with working-capital dynamics that may weigh on reported free cash flow in the near term. For sector peers, a similar cadence—solid demand with margin expansion but potential near-term cash-flow volatility—could persist if input costs stabilize and project backlogs normalize.

Takeaways for investors and sector watchers

• Profitability baton: A 210 basis-point margin expansion in the quarter signals pricing power and disciplined cost control—worth watching if peers can sustain it into H2.
• Cash flow watch: Six months of weaker operating cash flow and notably lower free cash flow raise questions about working capital timing and capital deployment in the second half.
• Outlook tilt: Raised adjusted EBITDA guidance suggests management is comfortable with a favorable revenue path, but the absence of a formal revenue forecast leaves a gap for revenue forecast visibility relative to consensus expectations.
• EPS trajectory: GAAP EPS of $0.38 and adjusted EPS of $0.40 reflect a healthy quarterly result; investors will compare these figures to street expectations (EPS consensus) as new estimates circulate.
• Sector implications: If Mueller’s performance embodies the sector, water infrastructure beneficiaries could see steady earnings growth, though sensitivity to interest rates and public funding cycles remains a consideration for peers.
